Tasty Planet: Back for Seconds is the sequel to Dingo Games' popular iPhone game, Tasty Planet. The sequel has many improvements over the original. Levels can now span vastly different object sizes; players can grow from the size of an amoeba to the size a galaxy within a single level. There is also a huge variety of new entities that players get to eat.

The game's story begins with the goo eating a time machine, causing him to be sent back in time. Players will eat their way through six different time periods: modern, Late Cretaceous (i.e. dinosaurs), Ancient Egypt, Ancient Rome, Feudal Japan, and the distant future. Each time period features a unique set of objects for players to eat. Mice, cats, Tyrannosaurus Rex, mummies, gladiators, and flying saucers are just a few of the hundreds of objects available for consumption.
